uWiki is a minimalistic wiki engine. All actions
are implemented in external scripts. These scripts
are wikified, and thus the wiki is extensible by
itself. All dynamic access is protected through
ACLs. Wiki content and Web content can be mixed in
the same directory hierarchy. Markup engines and
revision control are plugin-able. Currently,
asciidoc as the markup engine and git as the
revision control backend are provided.
Subdirectories can form independent sub-wikis with
own revision control. Features like distributed
pages that syncronize between wikis, spam
protection, and batch jobs to schedule mirroring
of other content (bittorrent, git, rsync, and
wget) are in planning.

updateThumbnails stores the thumbnails of photos
in a dot directory, stores thumbnails for
different applications and sizes, supports XV
thumbnails, supports generation of GNOME local
thumbnails as used by GQview, only generates
thumbnails if the original image has changed, and
removes thumbnails where the original file no
longer exists.

upnp2mrtg is a simple add-on for the MRTG (Multi Router Traffic Grapher). It can be used to monitor incoming and outgoing bytes of the external interface of the FritzBox DSL router. upnp2mrtg is a command line tool to gather statistics from an upnp enabled FritzBox DSL router. It is a lightweight shell-script for use with MRTG, so no underlying external software (with the exception of netcat) or libraries are required. Using bash-networking instead of netcat is also supported.

vidprofile is a collection of a few components
that finds the best way to create MPEG video with
mjpegtools. It fully characterizes mpeg2enc from
mjpegtools and helps answer the question: given a
file size limit, what are the best mpeg2enc
options (and values) to use that give the highest
possible quality MPEG video? mpeg2enc has an
abundance of command line options, and each one
tweaks the encoded output (some options tweak to
larger degrees than others). vidprofile offers a
set of tools to let the user fully test each of
the options in mpeg2enc and quantify the output
video's size and quality.

vlock is a program to lock one or more sessions on
the Linux console. This is especially useful for
Linux machines which have multiple users with
access to the console. One user may lock his or
her session(s) while still allowing other users to
use the system on other virtual consoles. If
desired, the entire console may be locked and
virtual console switching disabled.

vpn-shaper is a dynamic traffic shaper for
openvpn, poptop, and similar programs, using
iproute2. It allows shaping of traffic between
many users conected to one server, and it supports
different prioritiy schemes for different users
and different types of traffic. Trafic shaping
uses the HTB qdisc. Prioritization uses l7-filter
and ipp2p and some of the patch-o-matic
extensions. Classification of trafic in HTB
classes is done by using the IPMARC patch-o-matic
extension. vpn-shaper requires the IPMARK
patch-o-matic extension, connmark iptables match,
and HTB qdisc.

vxref provides integration of the xref tool into vim.
The xref tool is a cross referencing and refactoring tool with a free version available that parses C and Java code, and a paid version that parses C++. vxref brings solid auto-completion (as opposed to all sorts of flakey varieties such as omni-complete) and accurate code browsing with scope information to vim.
